Primary ExaminerWilliam E. Schulz Attorney-Jack M. Wiseman [5 7] ABSTRACT A cleansing solution for removing spots from cloth and the like comprising the following ingredients:

a detergent of polyethylene glycol ethers such as Union Carbide 15-5- 9, a9 mole ethylene oxide adduct of a secondary alcohol in the range of 10-30 percent by volume;

an acetate solvent of the group including amyl acetate, ethyl acetate, hexyl acetate and butyl acetate in the range of 10-30 percent by volume;

a suitable coupling agent for stability and as a clarifier, such as a glycol ether solvent, for example, Dowanol EB, in the range of 2 -IO percent by volume; and

water in the range of 30-80 percent by volume.

4 Claims, No Drawings SPOT REMOVER FOR WEARING APPAREL RELATED APPLICATION This application is a continuation in part of my copending application, Ser. No. 59,681, filed on July 30, 1970 for Cleansing Solution now abandoned.

BACKGROUND OF THE INVENTION The present invention relates in general to cleansing solutions and more particularly to a cleansing solution for removing spots from fabrics and the like.

Heretofore, in the dry cleaning of cloth, a vast variety of cleansing solutions were employed to remove a given spot on a trial and error basis. It has been known that in the neighborhood of 15 spot removing chemicals would be on a board for the purpose of removing a spot. Such chemical solutions have been known to damage the color and the fabric and were only partially effective.

In addition, the operator had to have previous exposure as to the identification of the fabric and would seek information as to the type of spot on the fabric, such as lipstick, tea, coffee, paint, food, et cetera so as to be able to apply a particular chemical solution found to be most successful for the particular spot and the particular fabric involved.

SUMMARY OF THE INVENTION A spot removing solution for wearing apparel and the like comprising:

a detergent of polyethylene glycol ethers in the range V of l-30 percent by volume;

an ester solvent of the group including amyl acetate, hexyl acetate and butyl acetate in the range of -30 percent by volume;

a suitable coupling agent for stability and as a clarifier, in the range of 2 %-l0 percent by volume; and

water in the range of 30-80 percent by volume.

While the exemplary embodiment makes reference to spot removing from fabrics, the cleansing solution of the present invention can also be employed on carpets, drapes, vinyl floors, ovens, appliances, automobiles, woodwork, tiles, glassware, floors and the like.

The cleansing solution of the present invention has been found to be particularly useful in removing latex or acryllic paints from fabrics while not removing water based vegetable dyes from fabrics.

By virtue of the present invention, a single cleansing solution can be employed to remove spots from fabrics without knowledge of the particular fabric or spot involved. Such spots could be caused by lipstick, blood, tea, coffee, paints, foods, et cetera. Thus, the need for many different chemical solutions has been obviated. The cleansing is achieved without damage to the fabric.

In addition to the foregoing, the work of the spot removing operator at a dry cleaning establishment has been simplified and facilitated. It may be used prior to placing fabrics in the dry cleaning machine, or it may be used as an additive for the dry cleaning machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Range By Volume Ingredients a detergent of polyethylene glycol ether l0%-30% an ester solvent l0%3 0% a coupling agent 2/z%l0% water 30%-80% The detergent is of the polyethylene glycol ether of an alcohol with a carbon range of C r-C with a ethylene oxide adduct of a range of 7-15 mole EtO. In the alternative, the detergent may be an ethoxylated alkyl phenol ofa carbon range of C -C with ethylene oxide adduct of 7-l5 moles EtO.

The ester solvent is of the group comprising amyl acetate, butyl acetate, hexyl acetate or ethyl acetate. Preferably, the acetate is amyl acetate.

For clarification and stability a suitable active coupling agent may be employed. The coupling agents could be a glycol ether solvent, such as Dowanol EB or its related esters of the glycol ether solvents class. The use of a coupling agent is optional. The coupling agent may also be an alcohol such as ethyl, propyl, methyl or butyl alcohols. The coupling agents serve as active stain or spot removing ingredients in that it removes hydrocarbon, grease, oil and similar stains.

The preferred embodiment of the cleansing solution of the present invention is as follows by volume:

a detergent of polyethylene In the preparation of the cleansing solution, the detergent, amyl acetate and the coupling agent are poured into a suitable receptacle. Water is then added and the ingredients are mixed well to form the cleansing solution..
